Pipe Marking Makes for Greater Safety in Industrial Installations

Pipes are quite common in large structures. Commercial and industrial enterprises employ this type of system inside the property. Refineries, chemical plants, and other factories that process and transport liquids and gases are some of the industrial enterprises that use pipes. In addition, water treatment plants use pipes to transport water into their system. Aside from liquids, compressed air are also transported using pipes. Large buildings such as hospitals, schools, and malls use a network of pipes to carry different components in and out of the structure. 

Pipes are made from common materials like steel or PVC. The pipes usually differ in function, shape, and thickness. Since buildings use a vast network of pipes, maintenance can be difficult especially when there are parts or valves which need to be turned off during check up. For this reason, it is critical that pipes are marked so workers can easily trace or locate problems. Apart from pinpointing the location of the problem, markings also help warn workers when the said pipes contain hazardous substances. 


Pipe markings help create a conducive environment for workers. People in charge with the pipes exactly know what they are dealing with just by looking at the texts marked on the pipes. Marking the pipe with visible label allow workers to easily spot or read warnings on the pipe. They can easily distinguish the function of the pipe as well as the components inside. The size of the lettering has to be such that it is clearly readable even from a distance. This is especially important when such piping is running at heights or at locations that are not easily accessible.

Apart from labels, text are also come in different colors. The pipes are usually coded with the right marking color. These colors are used universally so workers of different nationality can easily identify what the pipe is all about. Combination of colors are also applied to give specific warnings. These combinations are usually in the form of stripes or bands. 

For example, a pipe with yellow and black stripes means that it contains flammable components. You can see these codings in fuel depots. Green and white on the other hand mean that the pipe is carrying potable or cooling water. On the other hand, pipes with brown and white stripes convey that the system is carrying combustible components. Meanwhile, pipes with orange and black stripes convey corrosive or toxic components. Fire fighters rely on pipes with red and white markings. Blue and white combination means that the pipe transports compressed air. 


Standards are also followed when marking the pipe by following sizes of letters, length of labels, and color of the font. Of course, the size of the font is based on the size of the pipe so for small pipes the markings are half inch in size with length of 8 inches while large pipes have three and half inch fonts and fields of 32 inches. Markings are also placed on surfaces adjacent to all valves so the function is easily determined. The markings are also written or installed on either side of floor or wall penetrations. For pipes that run in a straight line, the pipes must be marked repeatedly. Usually an interval of 50 feet is observed.
